COMPARATIVE STUDY OF EFFECT OF BASALT, GLASS AND …

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Experimental Study on Unconfined Compressive Strength of ...

ABSTRACT: Understanding and predicting the intact strength of rock is very important in design of foundations, tunnels, and in other engineering projects. The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock.

form. Results of the unconfined compressive strength tests on basalt indicated that as the loading rate was increased from 1 to 1.60 x 107 psi/sec, ultimate strength, total axial strain, and Young's modulus of elasticity increased. Total diametral strain decreased as load­ ing rate was increased. Results of triaxial tests indicated that the
